Babies younger than 12 month of age who are not breast-fed
almost always need iron-fortified formula. The iron in human milk is much more
easily absorbed by infants than the iron in cow's milk. Formula-fed babies can
become iron-deficient if iron-fortified formulas are not used. Iron deficiency
may cause severe complications in babies, such as weakness, abnormal digestion,
and permanently reduced learning abilities.
Some caregivers may be
hesitant to feed an infant iron-fortified formula because of concern about side
effects, such as gas or constipation. But these side effects have not been
proved by research, and low-iron formulas are not recommended as a remedy for
such symptoms. Although low-iron formulas are widely available, they should
only be used in extremely rare situations on the advice of your doctor.
After babies are 6 months old, they should be given iron-fortified
cereals along with breast-feeding or bottle-feeding.
